IMPROVEMENT IN FRUIT-JARS.

Specification forming part of Letters Patent No. 174,773, dated March14, 1876 application filed May 7, 1875.

To all whom it may concern Be it known that I, ARIEs P. BROOKE, of

Bayonne, in the county of Hudson and State of New Jersey, have inventeda new and useful Improvement in Fruit-Jars, which improvement is fullyset forth in the following specification, reference being had to theaccompanying drawing, in which- Figure 1 shows a sectional sideelevation. Fig. 2 is a side view of the stopper detached.

Similar letters indicate corresponding parts.

This invention relates to certain improvements in fruit-jars; andconsists of a fruit-jar provided in its neck with inclined grooves, andwith a gasket-supporting shoulder above the grooves and below the edgeof the mouth, in combination with a stopper having projections to engagewith the grooves, and a flange, against which the gasket is placed, aswill more fully be hereinafter described, and pointed out in the claim.

In the drawing, the letter A designates a stopper constructed accordingto my invention. The stopper has a cylindrical form, and is made hollowfor a portion of its length, in order to reduce its weight, the hollowportion being made, as shown, Fig. 1, to open toward the top of thestopper. Opposite to each other on the outer side of the stopper A areformed segments B, which are arranged one above the other, and inclinedin like directions, so as to form segments of a screw-thread. The letterO designates a fruit-jar, on the inner side of whose neck are formedsegments D, corresponding to those of the stopper A that is to say, thesegments D are arranged one above the other, and have a pitchcorresponding to that of the segments. of the segments of the jar D issuch as to admit of the passage between their ends of the segments B ofthe stopper, so that by a proper adjustment of the stopper it may bethrust 'into the neck of the jarA to a suflicient extent to admit of anengagement of the segments B D with each other.

When the stopper is thus inserted in the jar, and slightly turned to theright hand, the segments B D engage with each other and draw the stopperinward or downward, while The length at the same time the stopperbecomes locked in position. By returning the stopper, or turning it tothe left hand, it not only becomes unlocked, but by the screw-likeaction of thesegments is forced outward against .the resistance of theatmosphere, and the partial vacuum in the jar becomes broken, and thestopper can be readily removed.

The neck of the jar C is provided with an annular shoulder, at, on itsinner side, and below its top edge, to which shoulder is fitted anenlarged portion, F, formed on the upper end of the stopper. Between theshoulder and the enlargement F is interposed a gasket, G, ofindia-rubbero'r other suitable material. The gasket forms part of thestopper A, its inner edge being inserted in a groove, 0, formedimmediately below the enlargement F of the stopper, so that the gasketis not liable to become lost or displaced when the stopper is removedfrom the jar. The enlargement F is so arranged relatively to thegasket-shoulder d and to the segments B D that when it comes in contactwith the shoulder the segments are brought in a position to engage witheach other. In the upper edge of the stopper A are formed notches H H,in order to admit of looking or unlocking the stopper by means of awrench or key, the notches being opposite to, and. forming acontinuation of, each other. By this means an exceedingly firm union ofthe stopper with the jar may be produced.

By this arrangement I obtain a compact, strong, and durable fastening,and one which is not liable to work loose, nor toget out of order; and,furthermore, by arranging the gasket-supporting shoulder below the topedge of the neck, I am enabled to form said shoulder in the moldtogether with the segments D, so that these parts will be perfectly truein regard to each other, and by inserting the stopper, and turning it inthe proper direction, a tight joint is produced Without subjecting thejar to any further operations, such as grinding off its top edge.

The stopper is provided with a flange, p, which sets below thegasket-shoulder in the mouth of the jar, filling the same, and pre byturning the stopper in one direction it is locked, while by turning itin the opposite direction it is raised against the pressure of theatmosphere, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 28th day of April, 1875.
